    hi i did the manual way its working fine..but when i try to open phone app its crashing only after i change the language to english again its working fine..please help android version 5.1.1

  2. Saki

    Best solution for android succesful patch adb install, but still cant change the language and unauthroized manual adb installation.

    It’s likely that the device is no longer authorized on ADB for whatever reason.

    1. Check if authorized:

    2. Revoke USB Debugging on phone

    If the device is shown as unauthorized, go to the developer options on the phone and click “Revoke USB debugging authorization” (tested with JellyBean, Samsung GalaxyIII & Grand prime).
    after revoke, switch off developer option and ON again and enable debuging again then.

    3. Restart ADB Server:

    enter cmd > cd youradbpath (enter)
    then command
    adb kill-server
    adb start-server

    4. Reconnect the device

    The device will ask if you are agree to connect the computer id. You need to confirm it.

    5. Now just re-enter the manual command prompt and install automatic-adb too make sure patch succes

    note : better just off your wifi and internet on your android
